Drinking Makes It Harder for Your Body to Absorb Folate.
Alcohol could be a big problem if you’re trying to increase your folate intake. Normally, your body absorbs folate directly from your food. Alcohol disturbs this process, reducing how much folate is released into the blood. Additionally, alcohol affects how well the kidney filters blood, causing the organ to absorb more folate from the blood and release it in urine. Chronic and heavy drinking is even worse for folate absorption. Heavy alcohol use can harm your gut and make it more difficult for it to absorb folate. Chronic heavy drinking also affects the liver, which stores folic acid, and may deplete levels of the nutrient. By some estimates, as many as half of people who abuse alcohol have folate deficiency.
